You should be too busy to “do coffee,” while still keeping an uncluttered calendar.

Set and enforce an aspirational personal hourly rate. If fixing a problem will save less than your hourly rate, ignore it. If outsourcing a task will cost less than your hourly rate, outsource it.

Work as hard as you can. Even though who you work with and what you work on are more important than how hard you work.

Become the best in the world at what you do. Keep redefining what you do until this is true.

Apply specific knowledge, with leverage, and eventually you will get what you deserve.

When you’re finally wealthy, you’ll realize that it wasn’t what you were seeking in the first place.

And here are a few of Naval’s observations that Noah Madden highlights:

“The secret to public speaking is to speak as if you were alone.”

“The fundamental delusion — there is something out there that will make me happy and fulfilled forever.”

“Even today, what to study and how to study it are more important than where to study it and for how long. The best teachers are on the Internet. The best books are on the Internet. The best peers are on the Internet. The tools for learning are abundant. It’s the desire to learn that’s scarce.”

“A rational person can find peace by cultivating indifference to things outside of their control.”

“The power to make and break habits and learning how to do that is really important.”
